[The value of CT examination for diagnosis of postoperative colonic cancer recurrences using bi-contrast and mono-contrast enema and air].

: The material comprises a group of 33 patients in whom CT check-ups revealed the presence of recurrence after colon cancer surgery. CT examinations were performed using 3% gastrographine contrast enema, air insufflation and filling the intestine with water with the patient lying on the back and abdomen. The anastomotic recurrence was found in 11 patients (33.3%), peri-anastomotic in 14 cases (42.4%) and distant in 8 patients (24.3%). The authors emphasise the value of air insufflation in visualising the anastomotic segment and thickness of intestinal walls. They are consistent with literature data in pointing to the purposefulness of target biopsy, guided CT and determination of the level of blood serum carcinoembryonal antigen in revealing recurrences.
